Should i give both group or one group

depends on your capability , if you are good struggler then go for both groups ,

if you go with only one group then time advantage milta , aaraam se complete karsakte , no tension , ................... both group ka percentage is lower than the group by group

Suggest all we need , Ask with " your friends , teachers " ..........................

Time is Super Man :D ,  IF YOU KILL TIME , TIME WILL KILL YOU
